How do I glue roofing membranes?

Pour the cold glue onto the substrate in a zigzag motion. Use a floor squeegee to spread the glue over the entire width of the roofing membrane. You will need about 1 kg per m2. Unroll the roofing membrane over the glue and press down. Make sure some glue protrudes from under the roll onto the seams. This seals the seams and guarantees a waterproof seal. You can sprinkle slate granules on the seams afterwards to give your roof a beautiful finish.
